Hanisha Koneru resolved HDDS-1990.
----------------------------------
    Resolution: Not A Problem

Revoked/ Cancelled delegation token information is propagated to all OMs. Expired tokens are removed from DB individually by OMs. This will not have any effect on the operation as if an expired token exists in DB, the token validity check would fail.

We do not have to sync removal of expired tokens between OMs.
